This is a phase 2 prospective randomized trial investigating the impact of amniotic membrane placement over the neurovascular bundles after bilateral nerve sparing robot assisted radical prostatectomy on potency. The study will have a control arm that will follow standard of care surgery, without placement of any membranes. 70 men will be allocated to each arm.
The research study will involve follow up every 3 months for the first 12 months. After this the investigators will follow patients annually with prostate-specific antigen (PSA) measurements and an assessment of any secondary therapies for 5 years post-surgery.
Randomization of study patients will be done in equal proportion to Arm I (membrane placement) and Arm II (no membrane placement, standard of care surgery) using a permuted block design stratified by baseline SHIM score (\<17 vs. \>=17), and use of ANY erectile aids (Yes vs. No) in the last 3 months.
